[S] Change in osmo-ci[master]: jobs/ttcn3-testsuites-testenv: tweak description

by osmith

Hello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-ci/+/38459?usp=email to look at the new patch set (#2). The following approvals got outdated and were removed: Verified+1 by Jenkins Builder Change subject: jobs/ttcn3-testsuites-testenv: tweak description ...................................................................... jobs/ttcn3-testsuites-testenv: tweak description Don't link to osmo-ttcn3-hacks.git directly anymore, the wiki page that is also linked already refers to it. This shortens the boilerplate of the description with every one of these jenkins jobs. Instead of only displaying the arguments, display the full command so users can easily run the testsuite the same way it is running on jenkins. Omit the arguments --cache, --ccache, --log-dir, which only need to be adjusted for jenkins, for users the defaults make sense. Let the kernel line link to the related build-kernel job.

[M] Change in osmo-ttcn3-hacks[master]: ggsn: README: document how to run with testenv

by osmith

osmith has uploaded this change for review.

This should make it easier for users, in addition to testenv already telling which configs are available if trying to run the ggsn testsuite without the -c argument, and to the general help output in "./testenv.py run -h". $ ./testenv.py run ggsn [testenv] Using testsuite ggsn_tests (via alias ggsn) [testenv] Found multiple testenv.cfg files: [testenv] * testenv_open5gs.cfg [testenv] * testenv_osmo_ggsn_all.cfg [testenv] * testenv_osmo_ggsn_v4_only.cfg [testenv] * testenv_osmo_ggsn_v4v6_only.cfg [testenv] * testenv_osmo_ggsn_v6_only.cfg [testenv] Select a specific config (e.g. '-c open5gs') or all ('-c all') Change-Id: I49421151b199fa6536da784b6c412b03f3fdbd05 --- M ggsn_tests/README.md 1 file changed, 72 insertions(+), 4 deletions(-) git pull ssh://gerrit.osmocom.org:29418/osmo-ttcn3-hacks refs/changes/58/38458/1 diff --git a/ggsn_tests/README.md b/ggsn_tests/README.md index 71468d5..f40c4b0 100644 --- a/ggsn_tests/README.md +++ b/ggsn_tests/README.md @@ -1,9 +1,10 @@ # GGSN_Tests.ttcn -* external interfaces - * Gp: GTP (emulates SGSN) - * Gi: IP (emulates Internet) - * VTY +## External interfaces + +* Gp: GTP (emulates SGSN) +* Gi: IP (emulates Internet) +* VTY {% dot ggsn_tests.svg digraph G { @@ -16,3 +17,70 @@ ATS -> GGSN [label="VTY"]; } %} + +## How to run + +### osmo-ggsn + +osmo-ggsn with APN config [all](osmo-ggsn/osmo-ggsn-all.confmerge): +``` +$ ./testenv.py run ggsn -c osmo_ggsn_all +``` + +osmo-ggsn with APN config [v4_only](osmo-ggsn/osmo-ggsn-v4_only.confmerge): +``` +$ ./testenv.py run ggsn -c osmo_ggsn_v4_only +``` + +osmo-ggsn with APN configs +[all](osmo-ggsn/osmo-ggsn-all.confmerge), +[v4_only](osmo-ggsn/osmo-ggsn-v4_only.confmerge), +[v6_only](osmo-ggsn/osmo-ggsn-v6_only.confmerge) and +[v4v6_only](osmo-ggsn/osmo-ggsn-v4v6_only.confmerge): +``` +$ ./testenv.py run ggsn -c 'osmo_ggsn_*' +``` + +### osmo-ggsn + kernel GTP-U + +osmo-ggsn with APN config [v4_only](osmo-ggsn/osmo-ggsn-v4_only.confmerge) +and kernel GTP-U with a custom kernel: +``` +$ wget -O .linux https://jenkins.osmocom.org/jenkins/job/build-kernel-net-next/lastSuccessfu… +$ ./testenv.py run ggsn -c osmo_ggsn_v4_only -C +``` + +osmo-ggsn with APN config [v4_only](osmo-ggsn/osmo-ggsn-v4_only.confmerge) +and kernel GTP-U with Debian kernel: +``` +$ ./testenv.py run ggsn -c osmo_ggsn_v4_only --podman -D +``` + +osmo-ggsn with APN configs +[v4_only](osmo-ggsn/osmo-ggsn-v4_only.confmerge), +[v6_only](osmo-ggsn/osmo-ggsn-v6_only.confmerge) and +[v4v6_only](osmo-ggsn/osmo-ggsn-v4v6_only.confmerge) +and kernel GTP-U with Debian kernel: +``` +$ ./testenv.py run ggsn -c 'osmo_ggsn_v*_only' --podman -D +``` + +### open5gs + +``` +$ ./testenv.py run ggsn -c open5gs +``` + +## Related Jenkins jobs + +The jenkins jobs have the testenv arguments they use in their description. + +* [ttcn3-ggsn-test](https://jenkins.osmocom.org/jenkins/job/ttcn3-ggsn-test/) +* [ttcn3-ggsn-test-latest](https://jenkins.osmocom.org/jenkins/job/ttcn3-ggsn-… +* [ttcn3-ggsn-test-kernel](https://jenkins.osmocom.org/jenkins/job/ttcn3-ggsn-… +* [ttcn3-ggsn-test-kernel-latest](https://jenkins.osmocom.org/jenkins/job/ttcn… +* [ttcn3-ggsn-test-kernel-net-next](https://jenkins.osmocom.org/jenkins/job/tt… +* [ttcn3-ggsn-test-kernel-latest-net-next](https://jenkins.osmocom.org/jenkins… +* [ttcn3-ggsn-test-kernel-torvalds](https://jenkins.osmocom.org/jenkins/job/tt… +* [ttcn3-ggsn-test-kernel-latest-torvalds](https://jenkins.osmocom.org/jenkins… +* [ttcn3-ggsn-test-ogs](https://jenkins.osmocom.org/jenkins/job/ttcn3-ggsn-tes… -- To view, visit https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/38458?usp=email To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings?usp=email Gerrit-MessageType: newchange Gerrit-Project: osmo-ttcn3-hacks Gerrit-Branch: master Gerrit-Change-Id: I49421151b199fa6536da784b6c412b03f3fdbd05 Gerrit-Change-Number: 38458 Gerrit-PatchSet: 1 Gerrit-Owner: osmith <osmith(a)sysmocom.de>
